No one could answer my question so far:
If I decide not to open a video window (video_screen = 0 in the first frame) for my dedicated server, is there a way to prevent texture loading?

We have some very large textures. I don't want to increase the game size by saving every model twice, once with and once without skins, so I was wondering if there was a way for the engine to not load textures and only geometry.
Thanks...
